Troubled cyclist Lance Armstrong made headlines in January when he admitted to doping in a tell-all interview with Oprah Winfrey. Although Armstrong had previously denied such allegations, the public belief was that he was guilty. Another commonly-held belief about Armstrong is that he is far from a stand-up guy.In fact, actor Charlie Sheen recently slammed the former seven-time Tour de France winner in an interview. Sheen remembers Armstrong as being "kind of a douche" when the two met in 2005."He's kind of a douche. Wow, I didn't just say that did I? And I base that on meeting him, you know," Sheen said."He was talking to, I think he was talking to Sheryl Crow [Lance's former fiancée] at the time. I said, 'Hi Mr Armstrong, I'm Charlie Sheen. I just wanna say hello.' He looks at me, he's like, 'That's nice.'"Sounds like a great guy, huh? Sheen later added that if Armstrong had a better attitude that the public may be more forgiving of his transgressions."If he was a better guy I think in his life he'd be forgiven a lot faster and a lot easier," the actor claimed. "Kind of like me."Sheen recently recovered from his own struggles after he was fired from Two and a Half Men for a 2011 meltdown. The veteran actor is now the star of Anger Management.Take the advice from Charlie, Lance. Your family will thank you.
